Fluval Roma 240 L Stocking (Mbuna)

Hey!
I have a Fluval Roma 240 with two canister filters running combining to about 11x the tank volume filtered per hour. One of these filters is running with a spray bar and I also have a powerhead and airstones to ensure high aeration.
I want a Mbuna tank with less aggressive species as I’m a beginner cichlid keeper. I definitely want yellow labs and am thinking Pseudotropheus Acei (thinking ngara) and a Cynotilapia species to contrast with the yellow and blue. Does this stocking sound appropriate for what I want? Any other suggestions would be welcomed!
Also, how many of each species should I get and in what order should I introduce them as I can only get one at a time at the moment?
Thanks!
